Does rusty brake discs make brake discs wear out severely

Before solving the cause of rust in the car brake disc, we must first understand the cause of rust, so that we can find it in the future and also remind us to pay attention to these problems in the future.

Rusty car brake discs are mainly due to moisture. Some new cars have been parked in a place with high humidity for a long time, and the brake disc will have a circle of rust, and many new car owners will find that the brake disc is rusty after driving out on a rainy day, and they are very confused about whether it is the quality of the brake disc.

In fact, this is all normal, because the brake disc is made of steel, and because there is no anti-rust protection due to frequent friction, it is easy to rust. Under normal circumstances, if the rust is not very serious, you just need to drive out and brake a few times, and you don't have to worry too much.

However, if the rust is more serious, it should be noted that if the rust is serious, it will cause the surface of the brake disc to be uneven, causing the vehicle to vibrate or shake when braking, such as brake pad vibration, steering wheel vibration or shaking, body vibration, etc., which brings hidden dangers to safety. Therefore, it is necessary to maintain the brake disc every two months to avoid the rust of the brake disc from developing too severely.

Drive at a speed of 70 km/h on a flat road and brake several times to ensure that there is no abnormality. If there is still jitter, it means that the surface of the brake disc is uneven, and the brake disc has an abnormal situation, then it needs to be dealt with. It is recommended to go to a professional shop.

In general, rusty brake discs do not affect the brakes. When it is rusty, drive out and brake the car a few times, and the rust will be worn off by the brake disc. If there is still a place that has not been grinded, you can remove the steel ring and sand it off with sandpaper.

But if you encounter the next rainy day, you will inevitably get wet and rust again. This reminds you that when parking on rainy days, it is best to park in a place that does not get wet.

We are easy to ignore the problem of rust on the brake disc of the car, therefore, timely inspection must be done, and abnormal problems must be dealt with in time, after all, safety is the first. If the problem is not solved, or there are car failures and auto parts problems that have not been solved, search for "car repair and ask" on the WeChat public platform, and the technical team can answer you in detail for free.

First of all, let's understand the material of the brake disc, under normal circumstances, the material is gray cast iron HT250, which has high activity and is easy to oxidize in contact with air to generate ferric oxide Fe2O3, which is the rust phenomenon we see. If the brake disc is stained with water, galvanic corrosion can also occur, resulting in rust spots in a very short period of time. Especially in high temperatures.

Badly worn disc surface.

Yaw brake disc repair step.

1. First of all, the worn surface of the yaw brake disc is milled to remove the rough part of the surface and the depth of surface processing to ensure that the thickness of the yaw brake disc after processing is.

2. In order to ensure that the upper and lower clearance between the yaw brake disc and the yaw brake is within the range of 2-3mm, the upper surface of the yaw brake disc will be welded with a thickness of 8mm insert, the material of the insert is QT400, which is the same material as the yaw brake disc, which can ensure that the welding performance of the insert and the yaw brake disc is good, and the yaw brake disc is basically deformed after welding.

Why do some of the brake discs in cars rust easily?

The brake disc is rusty normally, and the brake disc is made of cast pig iron. In the case of long-term immobility and greater humidity, there will be rust stains, and when the rust is driven, drive out and brake the car a few times, and the rust of the brake disc will be worn off.

The solution to slight rust: the brake disc has a slight rust, which can be worn off by normal braking, the principle is to achieve the effect of rust removal through the friction of the brake pad and the brake disc.

Notes: 1) "Vehicle" refers to motor vehicles and non-motor vehicles.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicles" refers to vehicles driven by human or animal power and driven on the road, as well as motorized wheelchairs for the disabled, electric bicycles and other vehicles that are driven by power units but have a design maximum speed, empty mass and external dimensions that meet the relevant national standards.

Rusty brake discs are normal and have little to do with quality. After all, the brake discs of most family cars are made of cast iron, which is exposed to the sun and rain for a long time, and the working environment is harsh, especially if it is parked for a long time, the surface will be prone to some rust. Even if the new car of the 4S store is parked outdoors for a long time, it will also have this situation.

Although the rusty brake disc has a certain impact on the brake system, there is no need to be overly nervous and aggressive, and these problems can often be dealt with by the owner himself.

First of all, whether it is a new car can not be judged only by whether the brake pads are rusty, to be judged by the nameplate and the customs order, which is what we often call the procedures, in the establishment of 4S, the possibility of procedure fraud is almost zero, I have been in the industry for so long, I have not seen the establishment of the 4S shop fraud (except for small 3C and parallel imports), and now the cost of counterfeiting is very high!

Secondly, if the car to be picked up from the formalities is a car within half a year, then I would rather have a rusty brake disc when I pick up the car, there are two factors:

1. This natural oxidation is normal, especially after rain, which can occur within a few days. But if the car is too old, it's a different story!

2. After checking the procedures and nameplate to confirm that it is a new car, I will not mention the car with bright brake pads, because either this car has been driven (emergency braking a few times, this bit of oxide can be wiped off); Either the car has been in the showroom!

To sum up: on the premise that I can judge that the car to be mentioned is a new car, I will try to choose a car with rust, but not much! If it's too much or too bright, I'll ask for a replacement!

Rust of brake discs is common and normal because they are metal and have no protection, so they are directly exposed to the air, resulting in oxidative rust.

It is normal for car brake discs to rust, and here is a detailed introduction about it:

1. Slight rust:

Slight rust often occurs, and it is easy to cause slight rust after the car has been drenched in rain overnight, and the car has not dried after washing.

2. Severe rust:

If the brake disc has severe rust, then the entire surface of the brake disc has a relatively thick layer of rust. ”

Nowadays, many brake discs on vehicles are made of cast iron, of course, a small part is made of special materials, and it is normal for cast iron brake discs to appear rusty.

1. Most of the brake discs are made of cast iron, and there is no anti-rust treatment in order to increase friction, so it is easy to rust.

2. Whether it is a new or old car, if your car is parked for a few days and does not open, or if the water splashes on the brake disc when washing the car, the brake disc will also rust, and the rust of the brake disc is a very common phenomenon, and the rust of the brake disc does not mean that there is a problem with the car itself.

3. If the friction surface of the brake disc is slightly rusty, we can continue to lightly step on the brake on the safety road, and use the back and forth friction between the brake pad and the brake disc to quickly clean up the rust on the disc surface.

4. The rust on the brake disc is only oxidized and corroded for a short time, in fact, it does not affect the brake effect, the brake disc is made of cast iron, which is easy to have a chemical reaction with the oxygen in the air.

5. If you don't drive for a long time, the friction surface of the brake disc is more seriously corroded, and the rust can not be removed by driving to the safety road and stepping on the brake lightly, accompanied by the abnormal sound of stepping on the brakes, and the rust to the abnormal sound of stepping on the brakes, then you must go to the repair shop to do the light brake disc treatment.

I believe that many old drivers will notice that the brake disc of the car will rust, especially in rainy days or wet weather, after being parked for a long time in the wind and sun, this situation is even more serious.

Hello, as long as it rains and it rains for a few days, it will rust, just open it.

Hello! It is normal for the brake disc to produce a little rust when the vehicle is idle, and if the rust is very serious, it is recommended that you go to the 4S shop for inspection. So as not to have accidents, but also to give yourself a peace of mind.

Hello, it is normal for the brake disc to be rusted with water when the vehicle has been parked outside for a long time, but it is recommended to drive to the repair shop to polish it.

Hello, normal phenomenon, just run and run in for a while, thank you for your support to the car master, I wish you a happy life.

If you open it often, it's fine, and the inner circle won't rust.

Hello, it's normal.

It is normal for the brake disc to rust because the main component of the brake disc is iron (mainly steel), and it is normal for the iron to rust. After the vehicle is parked in a wet environment, or when driving after a car wash, or when driving on a rainy day, the brake disc can rust, and the metal will rust. If it is a slight rust, this will not affect the brakes of the car.

Normal, because the brake disc is iron, the car will rust if it is not driven for a long time.

The material of the brake disc is mostly cast iron, when it encounters wet and rainy weather, coupled with long-term wind and sun, if the vehicle is parked for a long time, its surface will naturally generate some rust, and these rusts will more or less affect the normal operation of the brake system, so it is necessary for us to dispose of the rust on the brake disc. 1. If there is only a slight rust on the surface, then yes.

1.The material of the brake disc is cast steel;

2.Cast steel has the same material characteristics as iron, and the exposed parts will be exposed to moisture in the air, which will cause rust over time.

Conclusion: Rust is inevitable when the brake disc is exposed, and the surface rust will disappear after a few brakes.

It doesn't matter. The rust of the brake disc does not matter, if the brake disc is rusty, it is because of a rust caused by water marks, which is a very normal phenomenon and does not affect the normal use.

Details:Rust of the brake disc is a normal phenomenon and will not affect the braking performance, so no special treatment is required, and normal driving is sufficient. After pressing the brakes a few times, the brake pads will wear off the rust on them and they will become shiny again.

Because the brake discs of most family cars are made of cast iron, iron is easy to rust when it encounters water, but it is only the surface that rusts. Because the surface can come into contact with the air, the oxidation reaction occurs, and the contact with the air is almost invisible, and the rust is very slow, so even if it is not opened for a long time, there is no need to worry about rusting the brake disc. Moreover, the place where we park cannot be wet all the time, and if it is not damp and there is no moisture, it will not continue to rust.

The material of the brake disc is mostly cast iron, when it encounters wet and rainy weather, coupled with long-term wind and sun, if the vehicle is parked for a long time, its surface will naturally generate some rust, and these rusts will more or less affect the normal operation of the brake system, so it is necessary for us to dispose of the rust on the brake disc. 1. If there is only a slight rust on the surface, then yes.

It is normal for car brake discs to rust, and here is a detailed introduction about it:

1. Slight rust: slight rust often occurs, after the car is drenched in rain overnight, the car is not dry after washing, etc., which are easy to cause slight rust. In this case, the rust can be removed by continuous braking while driving, because the brake disc is rubbed against the brake caliper during braking, and the rust will be worn off under repeated braking.

2. Serious rust: If the brake disc has serious rust, then the surface of the entire brake disc has a relatively thick layer of rust. Too stubborn rust can also accelerate the wear of brake pads, so you have to go to the repair shop to polish the brake discs.

Solutions for rusty brake discs:

The brake discs are cast iron and rust when they touch water. Moreover, it is a friction part, and it can not rust. When we brake, the rust is worn off.

Rust of brake discs is a normal phenomenon and has nothing to do with quality. However, it will still have a corresponding impact on the braking system, but don't worry too much. Everyone can handle this on their own.

If there is a layer of light rust outside, we can find a safe section of the road and apply the brakes a few times to deal with the problem.

If the rust is severe, we can dispense with it without the above method. At this time, we have to drive to the auto repair shop or 4S shop, ask the mechanic to remove the brake disc, and then sandpaper it to remove the rust on the outside.
